Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-design-critic scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Design Critic

Some sites are technically fine and still scream "an AI made this in one shot." This skill names exactly why and tells you what to change. It reviews the design and the copy, because generated-looking text gives a build away as fast as a centered hero and a purple gradient.

Use it as the finishing pass on claude-landing-composer output, on any vibe-coded frontend, or on a live site that feels generic. It pairs with the design tokens from claude-design-system-architect (audit against them when they exist).

Step 1 — Take in the target

A URL (WebFetch + screenshot), a local project (read the components/styles), or pasted code. Establish: what is this page for, who's the audience, and what's the one action it wants? A critique without the goal is just opinion.

Step 2 — Audit across dimensions

Go dimension by dimension and flag concrete instances, not vibes:

Layout & composition

  • Every section a centered stack? Three-identical-cards reflex? Predictable hero → cards → CTA with no rhythm? Symmetry where asymmetry would feel crafted? Cramped or uniform whitespace?

Color

  • Purple or default-AI gradients (the dead giveaway). Too many competing accents. Off-brand or arbitrary hexes not mapped to tokens. Contrast failures (check AA).

Type

  • Default system sans at 2–3 sizes. No real modular scale. Weak hierarchy. Generic pairing. Line length / line-height that reads like a default.

Spacing & detail

  • Uniform padding everywhere. No optical adjustments. Borders/shadows that are all identical or all heavy.

Motion

  • The same fade-up on every element. Motion that decorates instead of directs. prefers-reduced-motion ignored.

Iconography & assets

  • Emoji used as UI (replace with Lucide/Heroicons). Generic stock imagery. Placeholder logos left in.

Copy (review this as hard as the design)

  • AI tells: "elevate", "unlock", "seamless", "empower", "in today's fast-paced world", "we're thrilled to", "the power of", relentless em-dashes, every sentence a tricolon.
  • Generic value props ("the best way to X"), hedged language, "Learn More" buttons, "Welcome to {Product}" heroes, filler microcopy.
  • Flag the exact lines and rewrite the worst offenders.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
